I've got some large pipes in the basement that are about 4-6" in diameter. I think they were left over from a previous steam system but am not sure. I'm trying to do different things to make the heating system more efficient. I'm going to insulate these pipes...but before I do I wanted to make sure there wasn't justification to replace them. With what a plumber costs per hour I'm almost sure the answer is no, but they are rather long runs of piping and I'm basically heating up a good deal of "extra" water each time. Anyone else have any experience with this? Thanks.
